Function

The EJECT statement may be used to control page advance/page ejection.

Syntax Description

Two different structures are possible for this statement.

For an explanation of the symbols used in the syntax diagrams below, see Syntax Symbols.

EJECT - Syntax 1

EJECT

ON

[(rep)]
OFF

Syntax Element Description:

Syntax Element Description
EJECT ON/OFF (rep)
With Report Specification - Online and Batch Modes:
EJECT OFF (rep) Causes no page advance (except as specified with Syntax 2 of the EJECT statement) for the specified report to be executed.
EJECT ON (rep) Causes page advances for the specified report to be executed.
EJECT ON/OFF
Without Report Specification - Batch Mode only:

Without report notation (rep), EJECT ON/OFF may be used in batch mode to control page ejection between the output listings created during the execution of a program.

EJECT ON Causes Natural to generate a page eject between the source program listing, the output report and the message
EXECUTION COMPLETED
. This is the default setting.
EJECT OFF Causes Natural to suppress page breaks between the above output. EJECT OFF remains in effect until revoked with a subsequent EJECT ON statement.
(rep)
Report Specification:

The notation (rep) may be used to specify the identification of the report for which the EJECT statement is applicable.

A value in the range 0 - 31 or a logical name which has been assigned using the DEFINE PRINTER statement may be specified.

If (rep) is not specified, the EJECT statement will be applicable to the first report (Report 0).

For information on how to control the format of an output report created with Natural, see Controlling Data Output in the Programming Guide.

EJECT - Syntax 2

This form of the EJECT statement may be used to cause a page advance without a title or heading line being generated on the next page and without TOP/END PAGE processing.

EJECT [( rep )]

IF

LESS [THANoperand1  [LINES] [LEFT]

Syntax Element Description
(rep)
Report Specification:

The notation (rep) may be used to specify the identification of the report for which the EJECT statement is applicable.

A value in the range 0 - 31 or a logical name which has been assigned using the DEFINE PRINTER statement may be specified.

If (rep) is not specified, the EJECT statement will be applicable to the first report (Report 0).

For information on how to control the format of an output report created with Natural, see Controlling Data Output in the Programming Guide.

IF LESS THAN operand1 LINES LEFT
IF LESS THAN ... LINES LEFT Clause:

A page advance will be performed only when the current line for the page is greater than the page size minus operand1. The value for operand1 may be specified as a numeric constant or as a variable.

Processing

The execution of an EJECT statement does not cause any statements used with an AT TOP OF PAGE, AT END OF PAGE, WRITE TITLE or WRITE TRAILER statement to be executed. It does not affect system functions evaluated by DISPLAY GIVE SYSTEM FUNCTIONS.

EJECT causes a new physical page only. It causes the Natural system variable *LINE-COUNT to be set to 1 but has no effect on the setting of the Natural system variable *PAGE-NUMBER.
